2 volts across 100 kOhms produces 0.02 milliamps (or 20 microamps) of current. Ohm's law: Voltage = Amperes * Ohms, so Amperes = Voltage / Ohms.

If the current is 33 milliamps and the resistance is750 ohms what is the voltage?
24.8 Volts
How much power is dissipated by a circuit with 15000 ohms of resistance and 10mA of current?
15 KOhms times 10 mA = 150 volts. 150 volts times 10 mA = 1.5 watts.
How much voltage does it take to injure someone?
That is difficult to answer because there is no fixed answer. As an experiment put both terminals of a 9V battery on you tongue. It will not hurt you but you will surely feel it. Now put your thumb across the terminals of that same battery. Two things should now be obvious to you: 1) that even low voltages can "hurt" you under the right conditions, and 2) voltage is not the only factor that determines how harmful.
What is deadlier volts or amps?
The formula for amperage is Amps = Voltage / Resistance. As the voltage become higher so does the current that can flow through your body if you short across an electric potential. Remember that 1 amp is equal to 1000 mA. The following list is the tolerances that the body can stand. Less than 1/2 milliamp no sensation 1/2 to 2 milliamps, Threshold of perception 2 to 10 milliamps, Muscular contraction 5 to 25 milliamps, Painful shock (may not be able to let go) Over 25 milliamps, Could be violent muscular contraction 50 to 100 milliamps, Ventricular fibrillation over 100 milliamps, Paralysis of breathing resulting in death.
Why 380 volts line to line if connect line to neutral is 220 volts?
A voltage of 380 volts is a three phase voltage. On a three phase four wire system, each phase leg to neutral (grounded) will give you 220 volts. This voltage is obtained by dividing the phase voltage by 1.73, as the phase legs are generated 120 degrees from each other. Square root of three is 1.73 divided into 380 equals 220 volts.
8 volts divided by 40 milliamps equals?
0.2
What is 230 volts divided by 500000 oohms?
0.0005
How many amps is 450 watts?
450 watts divided by 120 volts equals 3.75 amps450 watts divided by 12 volts equals 37.5 ampswatts divided by volts equals amps
How LCR-Q meter differs from digital multimer?

At 12 volts how many watts is 30 amps?
Watts is volts times amps, so 12 x 30 = 360 watts
How many amps is in 6000 watts at 240 volts?
Watts divided by volts equals amps so 6000 divided by 120 = 50
If the current is 33 milliamps and the resistance is750 ohms what is the voltage?
24.8 Volts
How many amps are required for 100W light bulb operate on 110 volts?
amps equals watts divided by volts.
Can you use 12v 500mA adapter to tv antenna that has 12v 200mA?
YES!If you have a TV antenna amplifier rated at 12 Volts and 200 milliamps, you can use any power supply that will deliver at least 200 milliamps at 12 Volts. The important item is to keep the 12 volts at 12 volts. note: 200 milliamps is 0.2 amps. Even if you had a power supply that delivered 2000 amps at 12 volts you would be OK as it will only draw the 200ma that it needs.
What is stronger 4 amps or 12 volts?
Amps and volts are two different values so in your question they can not be compared. If you want to know which one can do the most damage to a human body then the amperage wins hands down. The following list is the tolerances that the body can stand. 1 amp equals 1000 milliamps Less than 1/2 milliamp no sensation 1/2 to 2 milliamps Threshold of perception 2 to 10 milliamps muscular contraction 5 to 25 milliamps painful shock (may not be able to let go) Over 25 milliamps Could be violent muscular contraction 50 to 100 milliamps Ventricular fibrillation over 100 paralysis of breathing.
How is twelve volts at five amps converted into milliamps?
12V 5A = 12V 5000mA
